Abstract: An antenna array system comprises a plurality of antenna elements arranged in an antenna array in a geometric shape. The antenna array system further includes a first sub-array that forms an interior of the antenna array and a second sub-array that forms an exterior of the antenna array. In addition, the first sub-array is a subset of the second sub-array. A number of antenna elements in the first sub-array is greater than a number of antenna elements in the second sub-array. The antenna array system determines an exact satellite location of a satellite within a solid angle of ambiguity using a first virtual pattern and a second virtual pattern.

Abstract: A diversity channel for data transmission is obtained by communication equipment. The diversity channel indicates communication resources that are assigned to the communication equipment, and is from a set of diversity channels that are consistent with codewords of a linear code. The communication equipment also transmits a data transmission using the communication resources indicated by the diversity channel. The diversity channel assignment could be determined, by network equipment for example, and information that identifies the diversity channel could be transmitting to the communication equipment. Such information could be explicitly or implicitly signaled to the communication equipment. A set of diversity channels could be generated directly as codewords of one or more linear codes, or additional operations could be applied to such codewords, and possibly other information that is not generated using a code, to provide a diversity channel set.
